## ✅ Recently Completed
- [x] **IMAP reliability: switched to UID-based commands**`_fetch_imap_emails` now uses `UID SEARCH`, `UID FETCH`, and `UID STORE` throughout. Sequence numbers are volatile (they shift on expunge), causing "Too many invalid IMAP commands" on strict servers (e.g. T-Online). UIDs are stable. The per-message `STORE +FLAGS \Seen` (redundant — RFC822 sets it implicitly) and per-message `STORE +FLAGS \Deleted` are replaced with single batch commands. Stale already-seen UIDs are re-marked `\Seen` in one command. Logout is now in a `finally` block so a mid-session `BYE` is handled gracefully.
- [x] **Dashboard redesign**: Replaced noisy "Recent Processing Runs" table with a per-account "Mailbox Status" view showing last-check status (OK/Error/Pending), relative timestamp, error messages, and lifetime counters. Stats cards updated to show all-time processed count and accounts-with-errors count.
- [x] **Provider logos now saved on account creation**: `provider_name` field added to `MailAccountCreate` and `MailAccountUpdate` schemas (backend and frontend). `ProviderWizard` now passes `provider_name` in its `onSelect` callback; `AddMailAccountModal` stores it so logos are displayed correctly on the accounts page.
- [x] **Fetch button UX improvements**: The "fetch emails" button on the accounts page now shows a "Fetch" text label for clarity, a tooltip explaining its purpose, a spinning "Fetching…" state during the API call, and a brief green "Queued!" confirmation after success.
